TL;DR: Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units.

TL;DR: In this paper, the authors presented the results from a survey of 25 Galactic globular clusters with the MUSE integral-field spectrograph, which provided unique multiplex capabilities in crowded stellar fields and allowed them to acquire samples of up to 20 000 stars within the half-light radius of each cluster.

TL;DR: In this article, the authors performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction and found one curious star at the main-sequence turnoff with radial velocity variations of the order of 100 km/s, indicating the membership to a binary system with an unseen component.

TL;DR: In this paper, the authors used multi-epoch MUSE spectroscopy to study binary stars in the core of the Galactic globular cluster NGC 3201 and found that at least (57.5'±'7.9'% of blue straggler stars are in a binary system.

TL;DR: In this paper, the authors used multi-epoch MUSE spectroscopy to study binaries in the core of NGC 3201 and found that at least (57.5+-7.9) % of blue straggler stars (BSS) are in a binary system.
